Abstract

Un bouton-poussoir utilisé dans un panneau de commande comprend un corps de bouton, un doigt pousseur et une âme. Le corps du bouton possède un espace creux formé dans une partie intérieure de celui-ci ainsi qu'une partie de soufflet formée autour d'une partie latérale de celui-ci. Le doigt pousseur est saillant vers le haut depuis une surface extérieure d'une partie terminale supérieure du corps du bouton afin de recevoir une force de poussée. L'âme est retenue dans l'espace creux et fixée au niveau d'une surface intérieure de la partie terminale supérieure fermée. Lorsque la partie de soufflet du corps du bouton est comprimée de manière élastique par une force de poussée, une autre partie terminale de l'âme dépasse de la partie terminale inférieure du corps du bouton et lorsque la force de poussée exercée sur le doigt pousseur cesse, l'autre partie terminale de l'âme est retenue dans l'espace creux.
